I woke up one morning and my throat felt tight. I had been anxious before. I do not feel swallowing my saliva. But I can eat without a problem. It feels like my throat is closed. I tried valium which did not work. Now, I am on flexeril. I also hear a pulsing sound in my ear. What would be the proper treatment for this? i even had an endoscopy done and nothing showed up. I have not recieved a diagnosis. what do i do?
